Fire Sentry Smoke Alarm - Micro Profile

(Please ignore the little green Jack's price label! This item is free!) Manufacture date on back: Sep 3, 2021. This is a Fire Sentry i9040 smoke alarm with a micro profile design. It's battery operated and includes a 9V battery. Features include a test button, low battery indicator, and easy installation. Giving away two of these. You can get the other one also if you answer the other listing as well, but it's okay if you only want this one. Package was unopened, but I had to open it to look at the manufacture date.
